I think the point of going private is more a value and to some extent a political statement. A strong majority of people don’t like having their data taken or collected, but most don’t take actions to protect themselves for many different reasons.
But the privacy community do have a voice and by doing all the efforts to go private and by educating and making people aware that there are choices, the more people switch, the more it sends a message not only to the market, but to governments as well.
There’s always a risk of zero-day exploit on basically anything that could theoretically make anyone vulnerable. There could even theoretically be stuff installed on hardware that we wouldn’t know about and would make us all vulnerable. But even then, it’s worth it IMO, because the more people switch, the more it has an actual impact on society as a whole with the message it sends.
